PURPOSE:To provide a light, compact, economical and high reliable fuel injection device for distributing fuel of the maximum oil sending pressure 2000 atmospheric pressure by providing a barrel which has oil supply holes corresponding to integral times the number of engine cylinders having each a plunger slidably fitted and permitting the plunger to rotate and reciprocate by integral times of the number of engine cylinders. CONSTITUTION:When a plunger 30 descends, fuel in a chamber 36 is sucked from a spill port 32a through a hole 32 to the upper portion of a slide hole 35 in a barrel 34. The pressure of this fuel is increased gradually by the ascending of the plunger 30 when the spill port 32a is closed by the lower end face 37a of a adjusting piece 37 and then compression begins. And when a predetermined pressure is reached, an oil sending hole 38 coincides with a groove 31 for example, fuel is sent from there to a fuel injection valve in one cylinder of four cylinders to be injected into the cylinder. |
